High-quality copper production for ozygen-free copper and superconducting alloys production

摘要：

It was proved that the founder of process selective converting process of copper mattes was Karabash copper plant engineer Koljasnikov (Russia,1913). The new method of blister copper deep refining is considered. This process include white matte fire refine ment from bad impurites and their transfer to the first portions of blister copper,and continious removal it from reaction zone.Procedure is equivalent to impurities removal at extraction nomber n tending to infinity. Thus bad impurities removal from white matte is close to 100%.White matte converting will allow to produce higher quality copper anodes. The attantion is paid to necessity of deeper researching of copper mattes selective converting,including nikel-rich mattes.
